Why are people saying Chum was using KVM?

People claim that Chum made it to top five because of KVM. But Chum was genuinely entertaining and a kind person who deserved her position. I get that KVM helped her move from the kitchen and open up more but I believe that Chum didn’t use KVM. They both mutually benefitted from the relationship in BB house. In fact I feel like Chum’s North East supporters also voted for KVM in the last 10 minutes to help him win. Imagine the amount of votes KVM got because of Chum. KVM also got more footage due to his romance with Chum. So what’s up with this idea that Chum used him?? KVM is not a little kid, if Chum was using him for clout I am sure he would realise. He is in his 40s and has had relationships before, he has the wisdom and experience to spot if someone is using him/ not interested in him.
